    Howdy,:)

    I had found an old schematic posted in an edition of the journal of chemical education from september of 1969.
    http://pubs.acs.org/doi/abs/10.1021/ed046p613

    Everything it is okay with me. I can understand all, except one thing. :confused:

    I know this is basics regarding full wave rectifiers when working with AC.

    I can't find the datasheet for this diode ISJ150. Did anyone on this forum have heard of these?. Where i can find an equivalent?.

    Assistance on this matter will be kindly helpful for me.:)

    I would use a 1N4002 through 1N4007.
    You could probably use a 1N4001, but they're only rated for 50v. 1N4002 is rated for 100v.

    Yes, don't use a 1N4001 as the reversed voltage on the diode reaches 56V in the circuit because of the filtering capacitor.

    Okay i will try to find the 1N4007 at my local electronics store. Although i have been unable to find the datasheet belonging to that diode. It seems 4007 will make a good replacement.

    Apparently, the ISJ150 used to be stocked many years ago by RS Components in the UK. I have no idea who originally manufactured it.
